Factual error: When Sydney goes to Uzbekistan, it isn't Uzbekistan. The restaurant where the meeting occurs is not anything made by Uzbeks, and it is too remote to be made by foreigners. The land around is also very lush, unlike anything in the deserts of Uzbekistan. The people are speaking Arabic, instead of Uzbek and Russian, and the sign on the wall is also Arabic. The guards are also wearing what appears to be a Russian uniform, even if the badge is correct.

Throughout the show, the number 47 appears many times. There are multiple room 47's (where Syd found the Circumference in season 1 and the room in her memories from season 3, among others.), there are 47 Rambaldi artifacts, and page 47 of the Rambaldi manuscript was the page that had Sydney's picture on it.
